UE4 mesh problem?

How can I solve this problem?

You will have to be more specific than that. What specifically is wrong with that mesh?

The mesh does not look like it appears in the content table and the texture does not load. I also noticed that the shader does not load after installing the mesh.

The material for that mesh is missing.
You will need to open it in the static mesh editor and apply a material.

If there is a material applied, it is most likely not showing up due to a material compilation error.
